T 0 all 'whom t may concern:

Be it known that l, @mirino Hurra, acitizen or `Foland, residing atChicago, in .the

`county of Cool; and State vof illinois, have invented certain new4 anduseful improvements in Adjustable iframes, which the vfollowing is aspecific-ation.

This invention relates to certain vnew and `useful improvements inadjustable fra-mes,

particularly adapted for being adjusted in size to accommodate picture,mirrors or the like of various sizes. j

rihe primary object of the invention is -to provide a very simple anddurable fo-rm of adjustable frame of the above size wherein the naturalmechanical construction of the device provides an ornamental appearanceand means for obtaining a practical change in the size of the frame inan expeditious and simple manner.

Another object of theyinvention is to provide edicient means formaintaining the desired adjustment of the frame.

With the above general objects in view and others that will appear asthe nature of the invention is better understood, the same consists ofthe novel form, combination and arrangementI of parts hereinafter morefully described, shown in the accompanyingdrawingv and claimed.

ln the drawing, wherein like reference characters designatecorresponding parts throughout the several views, A

Figure 1 is a front elevational view of an adjustable frame constructedin accordance with the present invention,

Figure 2 is a side or edge elevational view of the device shown in Fig.1,

Figure 3 is an enlarged sectional view taken on line Ill- 111 of Fig. 1,and

Figure 4 is a perspective view of one of the members. employed forreceiving securing bolts to maintain the frame in adjusted condition.

Referring more in detail to the several views, the present inventionembodies an open substantially rectangular frame composed of a pair ofside frame'members 5N a top frame member 6 and a bottom frame 7, each ofwhich is of lazy tong construction involving a series of pivotally iconnected cross stripsS whose pivots are indicated by the referencenumeral 9. The adjacent ends of the side, top and bottom mem-` bers 5, 6and 7 are pivotally connected by oblique corner strips 1 0 which arepivotally byl the numeralll' to the adjacent end of `the adjacent lazytongframeA member.` A "substantially rectangular frame involving`effectively connected side, top' and bottom frame members, is thusprovided, and ornamentation may be provided vby means of the ornamentalcorner members 12 rigidly secured to" the obliques-trips 10 betwee'nthe'adjacent ends ofthe frame members and eX- f inlener 'attached at eachend latv two points denoted tending transversely of said strip 10 as fshown. prise three substantially parallel strips of a desiredconfiguration rigidly secured in spaced relation by transverse braces orcross bars 13, vthe outer endsof these strips being The ornaments 12 mayeach compointed and the twooutside strips being of the same length,while the intermediate strip `is the longer to give a rectangularap-pearance. It will be obvious that by forcing the two side framemembers toward each other the width of the framev may be varied withinconvenient limits while 'a similar movement of .the top and bottom framemembers will lessen the length of the frame.

On the otherv hand separation of Athese frame members will enlarge theframe as is job vious. y

ln order to maintain the frame in av desired adjusted size, an angleiron 14 is 'employed at each corner of the frame and comprisesa centralportion rigidly fastened to one of the corner oblique strips 10 withopposite4 legs 15 extending at an obtuse angle to the intermediateportion of the angle iron and provided with a longitudinal elongatedslot 16.` f

The next to the last pivot member at each end of each of the lazy .tongframe members is in the form of a bolt 17 having a wing nut 18 threadedthereonv and freely extending through'the slot in the adjacent larm ofthe adjacent angle iron, whereby upon tightening of the wing nut, thelazy tongframe members will be maintained in adjusted condition toprovide for retention of the frame in the desired size. Thus, by theloosening of eight wing nuts, two at each 'corner of the frame, theframe may be changed in size and when placed in the desired condition,may be so maintained by again tightening said wing nuts, the resultantstructure being quite lrigid and presenting a unique and ornamentalappearance. Spaced a suitable distance apart upon the back wall of theframe are picture retaining clips 19. t

From the foregoing description it is believed that` the constructionand.operation as well astfhe-fac'lvantages of the present iiivention willbe readily understood and appreciated by those skilled in Vthe art.

Minor changes may be n'iadein the invention without departing from the.spirit and scope of the invention as claimed.

What I claim as new p Y *i An adjustable frame of the class describedcomprising'apair of side members, a top `and la bottom frame member7said frame inem# bers being all of lazy:tong-construction and pivotallyconnected in end to'end relation to :provide 4an open substantiallyrectangular ra1ne,thefsa`id frame having picture retaining cli-psthereon meansgassociated with said frame members to 'hold the sameagainst exl tending or collapsing, the connections between the ends ofsaid frame members c'o'mymembers against 4accidental extension orcollapsing .involving angle irons rigidly fastened to 'the obliqueiframe member connecting strips and having arms at opposite endsextending at an obtuse angle and provided with longitudinal elongatedsl'ots,\said frame members involving 'pivot membersnear each end thereofin the nature of bolts Vwith wing nuts thereon, said bolts'extendingthrough the elongated slots of the angleiron arms, whereby tighteningVof the-.wing'n'uts lwill bind the parts to prevent the collapsingorextension of the frame members. l
